Abstract

Selon l'invention, un piège à air comprend un corps possédant un espace intérieur hermétiquement fermé présentant une paroi interne, un axe central, et une entrée et une sortie disposées sur l'axe central. Le piège à air comprend aussi au moins une protubérance disposée dans l'espace intérieur et couplée à la paroi interne. La ou les protubérances s'étendent de la paroi interne en direction de l'axe central avec un bord interne situé très proche de l'axe central.
